Sen. Elizabeth Warren on Thursday pledged to push Capitol Hill leaders for infrastructure investments and offered her support for high-speed rail linking major cities in Massachusetts.

"We need a train that runs from Boston to Worcester to Springfield," Warren, D-Mass., said during an "office hours" event at the Worcester Public Library.

Her mid-day appearance drew a crowd of about 150 people, many of them enthusiastic supporters.

Sen. Eric Lesser, D-Longmeadow, has pushed for a feasibility study of high-speed rail connecting Springfield and Boston. Gov. Charlie Baker vetoed a bill calling for the study and has pushed for a broader review of transportation options.

In a sit-down with Massachusetts reporters and editors earlier in the day, Warren was asked if she saw infrastructure investment as an area of common ground with President Donald Trump, who has said he will press for a $1 trillion infrastructure plan.

Lesser has asked Trump to include funding for east-west rail service as part of his plan.

"It starts out looking promising," Warren said of Trump's proposal. "The problem is where he's gone with it. What he's describing is a lot of tax breaks, rather than real money going into infrastructure projects."
